Huge can of worms. Letting student athletes profit from their image just establishes P-5 football and basketball as professional minor league sports. I don't care about minor leagues.
I'll be happy if collegiate athletics becomes college oriented again. Those that are so valuable and too special to participate can just jump straight to the pros. Many already jump ship after a year or 2 and it's a joke to refer to them as students. It'd be cool if the best schools attracted the best of the tier that doesn't go straight to the professional route. Let the Ivy League, Vandy, Stanford, Notre Dame, etc. be the best athletic programs.
